Increasingly, Alexander Clauss’ mobile opus is the Swiss Army Knife of browsing on the iPad, iPhone and iPod touch. With Dropbox, Firefox Sync and Private Browsing Mode integration, as well as extensible add-on functionality via modules, iCab is the way to get things done on the go.

Spend a minute thinking about what Mobile Safari doesn’t have and you’ll basically come up with a list of the things that distinguish iCab. Thereupon, Alexander Clauss shipped iCab Mobile 5 (iTunes, $1.99) at the end of August and the bullet points read pretty much like those for a current desktop browser release:

• Firefox Sync (read only)
• Do Not Track header support
• Site specific Browser UserAgent configuration
• Timed private mode user data deletion (forget it and it’s gone)
• New modules: SpringPad, PDF conversion, native Twitter app, EverRead
• Read all of the changes in the version history

Add in all of the stuff that iCab Mobile already does — Evernote and Facebook modules, Dropbox integration, fullscreen mode, best of class tab management — and you really should just get it, because it will boost your productivity if you use it.

And, the killer feature? Scrollbars.
